newtype Biap (bi :: Type -> Type -> Type) a b Source #
Pointwise lifting of a class over two arguments, using
Biapplicative
.
Classes that can be lifted include Monoid
, Num
and
Bounded
. Each method of those classes can be defined as lifting
themselves over each argument of Biapplicative
.
mempty = bipure mempty mempty minBound = bipure minBound minBound maxBound = bipure maxBound maxBound fromInteger n = bipure (fromInteger n) (fromInteger n) negate = bimap negate negate (+) = biliftA2 (+) (+) (<>) = biliftA2 (<>) (<>)
Biap
is to Biapplicative
as Ap
is to
Applicative
.
Biap
can be used with DerivingVia
to derive a numeric instance
for pairs:
newtype Numpair a = Np (a, a) deriving (S.Semigroup, Monoid, Num, Bounded) via Biap (,) a a
